Large capacity powder fertilizer production line

When producing powdered organic fertilizer, bar-stack fermentation is generally used, that is, ordinary stack-type fermentation.

When the moisture content of the raw material is too low, water or livestock and poultry urine should be added to increase the moisture content. When the water content of the raw material is too high, solid-liquid separation should be adopted, or the method of adding auxiliary materials should be used to reduce the water content. The auxiliary materials can be straw, peanut shells, and other plant residues. The final moisture content should reach 45%-50%.

After the ratio of the raw materials is good, it should be fully stirred and evenly distributed, put into the stacking tank or stacked into strips, 2 meters wide and 1 meter high. Or determine the size of the stack according to the existing turner.

Turn over the stack with a trough turner. When the temperature reaches above 60°C, turn over and toss every 2 days. After 10 days of fermentation at 60°C, the fermentation work is completed.
